About Loukman

PHP/Symfony developer specializing in B2C e-commerce and asynchronous architecture. I designed, delivered, and monitored a complete multi-tenant e-commerce platform in production: 15+ critical releases, 12+ complex business modules, migration to Symfony Messenger, and full internationalization in 3 languages.

My goal as a freelancer is to bring you cutting-edge technical expertise and complete autonomy to evolve your product frictionlessly.

My key areas of intervention:

  • Backend & Performance:Design of robust architectures with Symfony 7, PHP 8.3, Doctrine ORM, and drastic acceleration of response times through asynchronism (Symfony Messenger, Systemd execution queues).
  • Security & Multi-tenancy:Strict data isolation by domain name (Voters, Interception Event Listeners) and API security (JWT).
  • Fullstack Synergy:Design of REST APIs intended to power modern architectures under Next.js (Page Builder, dynamic rendering).
  • Incident Resolution & Customer Support:Design of diagnostic tools linking stocks, physical cash registers, and user accounts to eliminate production anomalies.

Let's work together to make your platform faster, more scalable, and perfectly secure.

  • SARL Evact
    Web Scraper
    E-COMMERCE
    January 2026 - May 2026 (4 months)
    Paris, France
    As a web scraper, I designed and implemented several data collection solutions for real estate agencies and other clients. I used three complementary approaches:
    • Scraping based on APIs (retrieval of structured and reliable data),
    • Scraping static HTML pages,
    • Scraping by simulating browser behavior (Selenium) for dynamic sites.
    I develop scripts in Python with Beautiful Soup and Selenium to extract, clean, and structure information (listings, contact details, prices, location, etc.), then deliver it in usable formats (CSV, Excel, database).

    These solutions have provided my clients with up-to-date data for market analysis, competitive intelligence, and prospecting.
